IMPROVEMENT IN RELAY MAG-NETS.

The Schedule referred to in these Letters Patent and making part of thelame.

To all whom it may concern Be it known that I,Lnnov1o CHARLES ADRIENJOSEPH Guror DARLINCOURT, of Paris, France, have invented new and usefulImprovements in Electro-Magnets; and I do hereby declare that the following is a full, clear, and exact description thereof, which willenable others skilled in the art to make and use the same, referencebeing bad to the accompanying drawing forming part of thisspecification.

My invention relates to improvement in arrangements of electro-magnet-sin telegraphic apparatus, and has special reference to the constructionor peculiar disposition of an armature pallet, when the same must serveas a relay, as hereinafter fully set forth.

In the accompanying drawing- Figures 1 to 4 represent variousarrangements or modifications of a certain plan of arrangement ofordinary electro-magnets, through which a permanent current would pass.

Figure 5 is a plan view of the same, with a pallet constructed andarranged according to my invention.

Similar letters of reference indicate correspondins parts.

a a represent ordinary electro-magnetic coils or spools, whose core ornucleus is made of soft iron.

12 represents a natural magnet, connected with the coils a a in suchmanner that the soft-iron cores of the said coils form the continuanceof the magnet b.

0 represents the pallet, the oscillating pivot of which works on themagnet 72, but its free end is set toward the point of junction of thecoils with the said magnet I).

Fig. 4 shows two coils, d d, substituted in place of the naturalmagnetb. In this case, a permanent current passes through the said coilsd, so as to magnet-ise their soft-iron core or nucleus.

When a current shall be transmitted in one direction through the coils aa, such a current will, for instance, cause the coil a to draw thepallet 0, while the coil a will repel it, and, as soon as such a currentwill be broken, the presence of the natural magnet 12, or itsequivalent, the coils d d, will generate a mag netic current in adirection opposite to that of the transmitted current, whereby the coila is made to repel, while the coil a will attract the pallet 0.

An electro-maguct of the above-described system, may be used forreversing the line current of a telegraphic apparatus, either as atransferring relay to transmit a new battery on the line, or as a singlere lay having charge to decompose the paper at the receiver withinautograp liic telegraphic apparatus, by a local battery which is causedto work by the said relay.

Fig. 5 represents the construction or peculiar dis- PL sition of thearmature pallet, when the latter must so we as a relay.

3 represent an insulated piece of the pallet c, which \vo between theelectro magnets a a','as before described.

The portion 6 f of the pallet produces the communicatio. with the localbattery A, while the other portion, 9 It, ofthc pallet, produces thecommunication with the ground, to discharge the line. I actually causethe line to con'imunicate before it enters the coils a a with theportion g h of the pallet, when such portion g h is in contact with thescrew This is the case when there is a current in the coils.

The pallet 0 will act as a trembler while the current lasts, therebypreventing the charging of theline and coils. When the current ceases,the pallet will travel in the direction of the arrow, and the portionefwill be in contact with the screwj. The local current will thereby becut oil', and may perform any required or desired function.

It will be seen that such disposition has a great importance, since itenables the continuous operation, while the current passes over theline.

Having thus described my invention,

I claim as new and desire to secure by Letters Patent- The pallet 0,provided with the insulated portion 0 f, substantially as and for thepurpose herein shown and described.
